. Specification of Letters Patent.

Patented Nov. 23, 1915.

Application filed December 28, 1914. Serial No. 879,248.

which the following is a specification.

This invention relates to metal .carlines for freight car roofs, andparticularly to the end connections thereof.

' The invention consists in a pressed steel bracket-member forconnecting the ends of a plates of the car. I I I Carlinesare subjectedto bending stresses throughout their length due to the weight ofthe-roof, and to combined bending and twisting stresses at their endscaused by the continual straining and distortion of the car frame inservice. The carline end connections to the side walls of the car mustbe such as to withstand'these stresses? Rolled dies, jigs, templets, andsimilar tools are required for making a complete line of sizes ofpressed steel carlines to fit-all cars it the end connections are madeintegral with the body portions.

"The object of this invention is an end bracket connection for a, metalcarline which is strong enough to resist the bending and twisting at theen'dof the carline,,wh1ch is light in weight and which takes up butlittle room.

A further object is an end bracket connection which is adapted to besecured to the ends of pressed steel or rolled metal carlines ofdifierent lengths,'whereby the body portion for each diiierent length ofcarline can be formed with the same tools, and special dies for eachdifferent length'of carline are dispensed with. 1

Further objects of the invention appear hereinafter in connection withthe descr ption of the embodiment of the invention shown. in theaccompanying drawings; and

what; the invention consists in is particularly set forth in theappended claims.

lathe drawings, in which the same'characters designate like parts in theseveral \IGWS, Figure 1 1S=fl plan View" of the end of ,a carline andpart of a side plate of a freight car, "howing a bracket connectionembodying the invention; Fig. 2 is a side view of the end of the carlineand bracket connection shown in Fig. 1, the side plate being shown incross-section; Fig. 3 1s a top or plan view of the bracket connection;and Fig. 4 is an inside face View of the same, showing the carline incross-section.

The carline 11 shown in the drawings is channel or U-shape incross-section, with of its side walls. The carline may be rolled, orpressed from sheet metal, and its ends are outturned lateral flanges12'along the tops I cut ofl to make its length slightly shorter than thedistance between the inside faces of the side plates of the car forwhich it is intended.

A bracket connection 13, which conforms in shape across its middle tothe under side of the carline at its ends, is riveted to each end of thecarline. The bracket connection has flat top walls l i-which support thelateral flanges 12 of the carline, and a fiat end wall 15 which isriveted to the side plate 16. The end wall is wider than the width ofthecarline, and the rivets for securing the bracket to the side plateare spaced apart sufficiently to afford a firm and substantialconnection between them. The edges of the 'top walls lei and ends of theend wall 15 are turned downward and inward, forming marginal flanges 17which extend across the angle between the top and end of the bracket andstiffen its corners. The flanges '17 and U-shaped middle portion of thebracket 13 give it an effective form to resist bending and twisting.

The invention is not restricted to the precise .forms and dimensions ofthe parts shown and described.

lVhat I claim as my-inve'ntion is as fol lows:

1. A carline'having a channel-shape body portion and end bracketssecured thereto, to, each of said brackets having a top wall conformingthroughout its length to the under side of the body portion of thecarline and spreading laterally outside of the latter y at its end, andan end wall transverse to thesaid body portion, and inturned flangesalong the side edges of the top Wall and ends of the end Wall connectingthem across the outer corners of the bracket, whereby said carline isadapted to be embodied in existing cars ithout removing the roof.

2. A carline having a channel-shape body portion and end bracketssecured thereto, each of said brackets having a flat top ,wall graduallyincreasing in Width from its inner to its outer end and provided with amiddle depression conforming to the under side of the carline and an endWall transverse to the carlin and coextensive with and depending Wallsat the outer corners of the bracket, and

means for connecting said bracket to the of December, 19H.

side plate arranged in the spaces between said inturned flanges andmiddle depression.

3. An end bracket for the carlines of freight cars, said bracket havinga top wall and an end Wall meeting at an angle, said top Wall having achannel formed in its middle extending through the end Wall forstiffening the bracket vertically under the end portionof a carline,said top wall being wider than said carline at the juncture with the endWall for stiffening said bracket laterally,

and edge flanges turned in along the edges of the top and end Walls andforming vertical'braces between theedgesiof said top and end Walls andforming vertical braces be tween the edges of said top and end walls forstiffening said bracket against twisting.
